The Union Railroad serves the steel mills of the Monongahela River Valley south of Pittsburgh. The Union is just 31 miles long but very busy. In 1951, they hauled 74 million net tons making URR the busiest freight railroad per mile of track in the world. Today, Union serves the USS Edgar Thomson Works which includes blast furnaces, a basic oxygen processor producing molten steel and a continuous caster. They also serve the USS Irvin Works which includes rolling mills and finishing lines and USS Clairton Works which converts coal into coke. Union Railroad received this group of hoppers in a trade with their sister railroad Bessemer & Lake Erie. This road name will be available in singles, and 2-packs, each in different road numbers.
